Saint Martin's Island is a territory of Bangladesh in the Bay of Bengal. It lies just a few km/miles off the southeastern corner of the country, near its border with Myanmar. With about 4,000 permanent residents, it is starting to participate in the growth of Bangladeshi tourism (both foreigners and domestic travelers). The island is known for its coral reefs as well as for its population of a rare species of sea turtle. You can check out this beautiful island form above in this drone video by Srabon_07.
